So I've been taking birth control for months now but recently I've been having this abnormal bleeding. The bleeding only happens when I'm aroused. I can go for days without a spot and as soon as I'm about to have sex it comes gushing out. I'm thinking this has something to do with my BC because it's only a recent thing. I missed a pill a few weeks ago and since then this has been happening. Is this normal when one misses a pill?
